The most amazingly tomboyish yet surprisingly girly pony in My Little Pony: Friendship is Magic TV show. She is sky blue with a long rainbow mane and tail. Her cutie mark is a cloud with a rainbow colored lightning bolt coming out of it.

Person 1: Awe man, this My Little Pony show is awesome... Theres this one pony, Rainbow Dash, she is fucking awesome!

Rainbow Dash is a main character from My Little Pony: Friendship is Magic. She is surprisingly tomboyish, doesn't care about how she looks. She is incredibly fast, and capable of pulling of a Sonic Rainboom, which requires a pegasus to accelerate to hypersonic speed. NOT to mention the Rainboom itself is a deadly shock wave.

However, she is not without her character flaws, she has a temper that may cause her to try and attack an antagonist who was being a jerk. Can be insensitive and arrogant. Even though the arrogance was down a notch after The Mysterious Mare Do Well, she still does have some. Not to mention she is quite brash.

But despite that, she never leaves her friends hanging, and cannot abandon them for her own heart's desire.

An awesome pegasus pony from My Little Pony: Friendship is Magic. Her coat is a pale cyan, her eyes are strong rose, her mane and tail are rainbow striped and her Cutie mark is a cloud with a rainbow-colored lightning bolt.

A main pony from My Little Pony: Friendship is Magic. This bitch is so fast, she was the first, and the last to ever do a sonic rain-boom. THE MOTHER-FUCKING SONIC RAIN-BOOM. YOU KNOW WHAT THAT SHIT IS? Only a Pegasus with mad SKILLS can pull that shit off.
And you just got 20% cooler in the 10 seconds flat that you read this.

RainbowDash is a pony character from the show My Little Pony. In the new generation (My Little Pony: Friendship Is Magic) RainbowDash has a rainbow mane and tail, blue body, blue wings, pink/magenta eyes and has a rainbow thunderbolt coming out of a cloud as a cutie mark. (Cutie Mark-A mark on the pony's 'flank' when they find a special talent they have. Usually gotten at a young age) RainbowDash is famous for being fast, braggy-ish, adventurous. And for her catch fraise "It needs to be about 20% cooler". RainbowDash and her friends are so famous that they take parts in Fanfics such as "Cupcakes", "Rainbow Factory", and "My Little Dashie" (I suggest you don't read Cupcakes or Rainbow Factory, it's a bit gory.)

Rainbow Dash is a character from My Little Pony- Friendship is MAGIC. She is a Pegasus (has wings). She is one of the main characters from My Little Pony- Friendship is MAGIC. She absolutely LOVES to fly, and especially win! A lot of times she is a show-off, and can be very boastful. If there is anyone more awesome than her, she'll be very jealous. However, her element is loyalty, she will stand up for her friends no matter what it costs her. If she had a choice of achieving your dream and helping your friends, she will never leave her friends hanging. Rainbow Dash lives in Cloudsdale, but spends most of her time in Ponyville with her friends. She is the only pony who can perform the SONIC RAINBOOM with her awesome flying skills. She and Applejack always fight on whether who is the most daring pony, however Applejack never brags about it. Rainbow Dash is brave and fearless!!!😁🏆

Rainbow Dash is a main character of the My Little Pony franchise, featuring as one of the Core 7.

She is a light blue earth pony with a pink, orange, yellow, and green mane and a pink, blue, and purple tail. She features a cutie mark of a rainbow stretching between two clouds. In 2009, during My Little Pony's "Generation 3.5" mass redesign, she was shown with a large ponytail in her mane.

Rainbow Dash is described as stylish and fashionable. My Little Pony calls her "The Glamour Girl of Ponyville." She is a kindhearted pony and is very interested in fashion and she also has a tendency to use say the word 'Darling' very often.

Note: Nothing is wrong here. I am aware that as of 2010 she was redesigned as an athletic pony. It isn't right, however, that all the definitions of her leave out this chunk of history, so I wanted there to be a definition on THIS Rainbow Dash as well. Though a lot of people will be tempted to downvote this because it's a side of the character you don't like, It's important that this be defined as well.
